Has the Lollipop OTA update stopped for Nexus 7 2013?

lollipop has been out for 3 - 4 weeks with most nexus 5 & 10 users getting it.
It did start roll out for the nexus 7, 3 weeks ago but most forums have stopped all info as to what happened. I own a nexus 7 2013 and still waiting.
Can you give any info on this please.
